Can you or anybody else tell me if a new set of springs really work ? Is there a significant difference with a new set ? For any of you that have installed new springs...let us hear from you.

Hey Rob, I do believe you are right about the car running to rich and the plugs are the evidence, lets hope the water sensor fixes it, if not i will try again, maybe change out the thermodine sensor. Bobby

Hey guys, I do have a FSM and it shows the air sensor to be in the airflow meter so that is out for now as they one i have is fairly new. As you said tomanyz's, it might be the water sensor. The FSM shows it to be on the front of the block and it shouldn't be to hard to change, also it shouldn't cost to much. I live way out in the country and go into town about twice a month, when i get the water sensor installed i will post the results. Thanks a lot to the 3 of you for helping me out, that's what makes this site the best one on the web for Z cars. Bobby Hunter

Hey Rob, that sounds good to me, I'll get an 02 sensor and change it out and see what happens, will take me a while until i get into town though. I am wondering of you have ever pulled one ? I checked my z and it looks like the original one and that got me to thinking about how hard it would be to remove. Thanks for the info, it's much appreciated Bobby

Hey Robb, thanks for the steer but the car is a fuel injected 75 280 Z. Got any steers on Fuel injected cars ? Bobby

My 75 280 started running rough about a month ago, after checking everything i know how to I still coudn't find the culprit, I then decided to start replacing all the usuals, ended up putting in new plug wires, distributer cap, rotor, fuel filter and cleaned the plugs [ had less than 5000 miles on the plugs ], the end result was that it ran a tad better but nothing significant, after thinking it over i decided to try a new set of plugs [ NKG's ] and i was not to hopeful about the outcome...well, i was surprised, it started right up and ran like a top. Forgot to tell you that when i pulled the plugs to clean them they were black all over. Back to the current situation; I was quite pleased that i had found the problem and fixed it...or so I thought. After a couple of weeks went by [ I only drove the car a total of about 20 miles ] I started it up and there was the problem again, i couldn't believe it ! Now why would it start running rough again when i had changed all those parts, that got me to thinking it must be fuel related but on a hunch i decided to have a look at a couple of the new plugs to see what they showed...yup, they were all black again, all 6 of them. Now you have the picture, with the above info can anyone tell me what the problem might be.... I suspect valve seals or rings or maybe something else, I hope it is something else like the flowmeter. When it runs rough i get blue gray smoke but when it was running well i just got a little blue gray smoke on startup...... I am stumped, any of you ever have the same problem and if so what was it ?

Anyone know if the manifold heat shield on a 280 Z is removable without having to pull the engine...if it is please tell me how. Bobby

Thanks for the info NH, I got the car new in Hawaii & the headpipe is the original and not an aftermarket item. It has me curious as to what the heatshield is supposed to be protecting. I will try to tighten it up but more than likely the bolts are frozen on...will replace them if need to. Bobby

While doing some cleaning on my 75 280 today i noticed that the exhaust pipe just below the firewall a cover over it, it has holes in it and is bolted on, I assume it might be a heat barrier but don't know for sure, it's very loose and moves around easily, the bolts are probably frozen on. Can anyone tell me what the purpose of it is and the consequences of removing it. Thanks. Bobby Hunter

:classic: Hey Mark, thanks a lot for the great photos and keep em' coming. Finally i get to see behind that dash, gives cause for concern as i see areas that would need attention on most Z's, especially mine. Don't have any preferences for future photos but more of the dash would be great and also maybe you can post photos of your dash reassembly when the time comes. Thanks again ! Bobby Hunter

I have always wondered what the back side of a dash looks like, also what the dash area looks like with the dash removed. If any of yous guys [ and gals ] have something like this how about posting it so we can all have a look...

Bryan, boy that hurts to find out they were what i was looking for and now are lost forever. Guess i was a day late and a dollar short. I'm sure it pains you too considering that you had them listed for a couple of months. That's kindly of you to check with the guy that might have some. I really only need the left door and of course prefer it to be in as good a shape as possible. My Z has 270 thou on it and the left door is just plain worn out, everything rattles and needs to be replaced and it's much cheaper and of course a lot less work to find a Z that is in better shape. I just joined the classic z cars site a day or so before i saw your post...looks like i should have done it sooner. Looking forward to hearing from you about the doors. Thanks, Bobby

Been hunting for a decent set of 2+2 doors for years, any chance you can find them at the dump ?

Hey Bryan, Do you still have those doors for sale ? My Z is a 75 2+2, will they work ? Bobby seahunt@gvtc.com
